Initialize.glsStruct {nlme} | R Documentation

## Initialize a glsStruct Object

### Description

The individual linear model components of the `glsStruct` list are initialized.

### Usage

    ## S3 method for class 'glsStruct':
    Initialize(object, data, control, ...)

### Arguments

`object` | an object inheriting from class `glsStruct`, representing a list of linear model components, such as `corStruct` and `varFunc` objects.
`data` | a data frame in which to evaluate the variables defined in `formula(object)`.
`control` | an optional list with control parameters for the initialization and optimization algorithms used in `gls`. Defaults to `list(singular.ok = FALSE, qrTol = .Machine$single.eps)`, implying that linear dependencies are not allowed in the model and that the tolerance for detecting linear dependencies among the columns of the regression matrix is `.Machine$single.eps`.
`...` | some methods for this generic require additional arguments. None are used in this method.

### Value

a `glsStruct` object similar to `object`, but with initialized model components.
